retrograde delivery of bmac (bone marrow aspirate concentrate) for congestive heart failure

Conditions: Congestive Heart Failure

Summary: the primary objective of this feasibility study is to provide clinical data to demonstrate the safety and activity of a concentrate of nucleated cells from bone marrow aspirate (bmac) produced with the harvest bone marrow aspirate concentrate system for treating patients diagnosed with congestive heart failure (chf).

to demonstrate that the infusion of bone marrow nucleated cells into the coronary sinus is safe as assessed by adverse event records. to assess the effect of the infusion of bone marrow nucleated cells on the clinical course of angina and heart failure as measured by qol questionnaire, minnesota living with heart failure, nyha and ccs classification and spect. to assess the effect of the infusion of bone marrow nucleated cells on heart function as measured by ejection fraction (ef) and left ventricular end-diastolic diameter (lvedd) by echo. to assess the effect of the infusion of bone marrow nucleated cells on the area of ischemia as measured by myocardial spect studies and echo.

Eligibility criteria:
inclusion criteria: * age ≥18 years and ability to understand the planned treatment. * patients with congestive heart failure * left ventricular ejection fraction ≤40% by echocardiogram, per echo completed 30 days prior to treatment * symptomatic heart failure nyha class iii or iv * able to comply with all study-related visits * able to tolerate study procedures, including bone marrow aspiration, spect, * able to give informed consent * negative for hcg with a serum pregnancy test * patients with controlled diabetes mellitus (hba1c \< 9.0%) * hematocrit ≥ 28.0%, white blood cell count ≤ 14,000, platelet count ≥ 50,000, * life expectancy of 6 months or more in the opinion of the investigator * patients requiring high dose corticosteroid therapy (more than 7.5 mg/day) with 1 month before the aspiration or 6 months after the infusion. * serum bilirubin, alt, ast ≤2.5 time the upper level of normal. * controlled blood pressure (systolic blood pressure ≤140 and a diastolic blood pressure of ≤90 mmhg) and established anti-hypertensive therapy as necessary prior to entry into the study * patient has received stable, standard medical therapy for at least one month with no new medications to treat the disease introduced in the last 3 months. * pre-existing condition (e.g. thromboembolic risk, diabetes, hypercholesterolemia are adequately controlled in the opinion of the investigator) * fertile patients (male and female) must agree to use an appropriate form of contraception while participating in the study. exclusion criteria: * female who is pregnant or nursing, or of child bearing potential and is not using a reliable birth control method, or who intend to become pregnant during the tenure of this study. * history of prior radiation exposure for oncological treatment. * history of bone marrow disorder (especially nhl, mds) that prohibit transplantation. * history of abnormal bleeding or clotting. * history of liver cirrhosis. * end stage renal disease (creatinine ≤ 3.0 mg / dl) and/or dialysis * acute myocardial infarction \< 1 week from treatment date. * active clinical infection being treated by antibiotics within one week of enrollment * inability or unwillingness to comply with the treatment protocol, follow-up, research tests, or give consent. * unable to have 250cc bone marrow harvested. * history of life-threatening arrhythmias, except if an automated implantable cardioverter defibrillator (aicd) is implanted * life expectancy \<6 months due to concomitant illnesses * known cancer and undergoing treatment; chemotherapy and/or radiotherapy * patients receiving treatment with hematopoietic growth factors (e.g., epo, g-csf) * patients who can not stop anticoagulation therapy (warfarin) 72hrs prior to bone marrow aspiration and infusion * patients who can not stop anti-platelet therapy (clopidogrel) 7 days prior to bone marrow aspiration and infusion * history of alcohol consumption exceeding the equivalent of 2 drinks/daily (1 drink = 5oz wine, 12oz of beer, or 1.5oz hard liquor) or illicit drug use within 6 months of screening. * patient who will require continuous high dose corticosteroid therapy (more than 7.5mg/day) within 1 month before aspiration or 6 months after injection procedure. * body mass index (bmi) of 40 kg/m2 or greater * patient receiving experimental medication or participating in another clinical study within 30 days of signing the informed consent * in the opinion of the investigator or the sponsor, the patient is unsuitable for cellular therapy * known allergy or sensitivity to contrast agents used in imaging procedures.
